Hull Form Design and Preliminary Evaluation of a Surface Planing Submersible Ship

摘要

HULL form design and performance evaluation of a Surface PlaningrnSubmersible ship (SPS) is presented. SPS is a new kind of multi-modernship which can sail in planing mode at high speed on the surface andrncruse underwater at low speed. A novel ballast channel system isrndeveloped to provide quick and easy submerge-emerge process.rnHydrofoils are also used to provide dive force as well as motion controlrnsurface for SPSS. A finite volume method based CFD method, whichrntakes the influence of dynamic sinkage and trim into account, is used tornobtain an good prediction of the hull form resistance as well as a clearrnsimulation of the fluid flow in the ballast channel. Preliminary modelrntests are also carried through and verify the hull form design and therncalculation results.
